质量守恒定律

Then the writer gave a practical case of law of conservation of mass. The conclusion is that the learning mode of the new curriculum is useful not only in theory but also in practice, and it is popular with students.

然后，给出了"质量守恒定律"一节的教学方案，通过实施得出结论：新课程学习方式不仅在理论上是可行的，在实践上也是行得通的而且是深受学生欢迎的。

For that, using Darcy law, ideal gas state equation, mass conservation law and moment equation, the paper presents the pressure distribution equation in the porous media and lubricated film including hydrostatic and aerostatic porous thrust bearings (circular pad and rectangular pad), hydrostatic and aerostatic porous journal bearings and hydrostatic and aerostatic porous spherical bearings.

为此，本文利用Darcy定律、理想气体状态方程、质量守恒定律、动量方程以及相应的边界条件，给出流体在多孔质内部和流体薄膜内部压力分布方程，结果表明这两个流动域内部流体压力分布方程是相互耦合的。

By the law of conservation of mass, the principle of effective stress and the Darcys law as well as the equilibrium differential equations, a coupled mathematic model that included the terms of source and sink, and its corresponding direct coupled FEA model, for the analysis of groundwater seepage and stress were developed.

其次根据土体的平衡微分方程、质量守恒定律、有效应力原理以及达西定律建立了考虑源汇项的渗流场与应力场耦合数学模型，并且提出了直接耦合有限元计算方法。

Then the writer gave a practical case of law of conservation of mass. The conclusion is that the learning mode of the new curriculum is useful not only in theory but also in practice, and it is popular with students.

The circulation, consumption and reproduction of the trilogy have not only testified to its historical significance and literariness, but also invested it with new meanings.

该三部曲的流通、消费与再生产不仅验证了其历史意义及文学性，而切还赋予它以新的意义。

If he thought that he could buy me off, he would be wrong.

如果他认为他可以收买我，那他就大错特错了。
